Aniline contains which functional group?

Aniline is defined by an amino group (-NH2) attached to a benzene ring, making it an aromatic amine. This amino group is the functional group present, with the nitrogen bearing two hydrogens. The other options describe groups not found in aniline: a carboxyl group would indicate a carboxylic acid, a hydroxyl group would indicate a phenol, and a methyl group is just a simple hydrocarbon substituent. The amino group explains aniline’s chemistry, including its basicity (the nitrogen lone pair can accept a proton, though resonance with the ring reduces its basic strength compared with aliphatic amines).
